CAST CPXP-EP Core — XILINX FPGA Results

The following sample results from 1 and 4 link widths implementations of the core are shown below (at the required frequency of 125 MHz, with a single VC, no ECRC, max. payload 256B, 2kB Retry buffer and 4kB Receive buffer). Actual slice count dependent on percentage of unrelated logic – see Mapping Report File for details. Only PCI Express bus interface signals are routed off-chip for reported IOB.
